## Brilliant

Brilliant takes a different approach to learning: rather than watching long videos or reading dense textbooks, you build understanding by solving interactive problems. Lessons break big ideas down into small visual steps, so concepts in algebra, calculus, statistics, logic and Python become intuitive. The platform is designed for self-paced learners from roughly middle-school level up to college and beyond, and it adds a new AI tutor called Koji who asks guiding questions and sketches on screen to help you find answers yourself.

Beyond pure math, Brilliant covers computer science fundamentals, programming, data analysis and how modern AI actually works, including neural networks, tokenization and model reasoning. Each track uses mastery assessments that adapt to your level, revisiting weak spots and serving targeted practice so progress is measurable rather than vague. Real-world examples, such as image filters or password security, connect abstract ideas to everyday technology.

The platform is also used by schools and families. It is accredited by ACS WASC, certified under the kidSAFE/COPPA program, and offers classroom and teacher programs so educators can assign adaptive lessons and homework. For individual learners, the app is available on web and mobile, with progress syncing across devices.

**Pricing & Plans:** Brilliant uses a freemium model: a limited free experience is available, while a Premium subscription unlocks the full course library and unlimited practice. Annual plans are the cheapest per month, and there are separate school/classroom plans.

- **Interactive problem-based lessons:** Learn math, science, CS and AI through short, visual exercises that build intuition step by step rather than passive video watching.
- **Koji AI tutor:** A visual, interactive tutor that works on a shared canvas, asks guiding questions and gives hints without simply revealing the answer.
- **Adaptive mastery assessments:** Quizzes and reviews adapt to your level, tracking what you have mastered and resurfacing topics that still need work.
- **Coding and CS foundations:** Write and run real code to learn programming logic, algorithms, data structures and debugging skills relevant to the AI era.
- **Courses for schools and families:** Accredited classroom programs let teachers assign adaptive lessons, with kidSAFE/COPPA-certified privacy protections.

**Strengths:** Hands-on, visual format makes abstract concepts easier to grasp; Access to the Koji AI tutor that guides rather than gives away answers; Accredited and kidSAFE/COPPA certified, suitable for schools and families; Works across web and mobile with syncing progress

**Limitations:** Full course library requires a paid Premium subscription; Not a replacement for formal instruction or credentials; Some advanced or niche topics are not covered deeply

## CasperPractice

CasperPractice is a specialist study platform for the CASPer situational judgment test, the open-response admissions assessment created at McMaster University and used by hundreds of health-science programs. Instead of generic chatbot feedback, the product runs a dedicated scoring model trained on a large corpus of real candidate answers, so responses are graded against the scale evaluators actually use and placed in a quartile band.

The workflow mirrors test day closely. You open a scenario, watch or read it once, and the timer starts; you then type or record a video answer exactly as you would in a live sitting. Within seconds you receive a quartile ranking, notes on specific sentences, and a rewritten version of your answer that demonstrates the reasoning a top-quartile response would show. A practice-test mode groups scenarios into full-length simulations so you can rehearse stamina and pacing, not just individual questions.

The library is broad — every major scenario type is represented, including ethics, empathy, collaboration, resilience, personal experience and media-based prompts. Progress accumulates across attempts, which makes it easy to spot recurring weaknesses such as one-sided arguments or unsupported claims. Free users can try the questions with limited AI coaching, while the paid Pro plan unlocks unlimited scoring and the 4th quartile guarantee, subject to stated conditions like answering a minimum number of questions with the same email used for the real test.

**Pricing & Plans:** Freemium. A free tier gives access to practice questions with limited AI coaching (the first attempts are coached at no cost), while the Pro plan is a paid subscription that unlocks unlimited scored attempts and the 4th quartile money-back guarantee. Pricing is discounted periodically on the site.

- **Realistic question bank and full mock tests:** Work through hundreds of typed, video and media-based scenarios, or take complete simulations that reproduce the CASPer sections, question order and per-question time limits.
- **Purpose-built AI scorer:** Answers are graded by a model calibrated on a large set of real CASPer responses, returning a quartile estimate rather than vague encouragement, plus sentence-level notes on what weakened the answer.
- **Instant answer rewrite:** After each attempt you get a stronger version of your own response, showing how to hold competing perspectives and land on a clear position without sounding rehearsed.
- **Competency coverage tracking:** Attempts are mapped to the competencies CASPer measures, so you can see whether ethics, communication or collaboration is dragging your average down and drill the weakest one.
- **4th quartile guarantee on Pro:** Pro subscribers who meet the conditions (minimum answered questions, matching email, official results forwarded in time) are refunded or keep lifetime access if they miss the top quartile.

**Strengths:** Purpose-built scoring model rather than a generic chatbot prompt; Quartile ranking and rewrites give concrete, comparable feedback; Full-length simulations mirror the real sections and time limits; Bonus: large free question set and a money-back guarantee on the paid plan

**Limitations:** Value depends on the accuracy of third-party AI scores, which only the official provider can truly validate; The free tier's coaching is limited, so meaningful practice volume requires a paid plan; Video-response practice still cannot replicate the pressure of a live proctored sitting
